Transitioning to a world powered by renewable energy is key to tackling climate change. Here you can find the latest good news related to our clean energy transition, covering wind, solar, green hydrogen, hydropower, and more.
Rapidly retrofitting old buildings is key for climate goals - Here's how to do it
Buildings account for about 40 percent of annual global carbon emissions. In order to meet our climate goals, every building on the planet will have to be net-zero by 2050. But since most of the current buildings will still exist then, a massive number of homes will have to undergo retrofits in Read More...
Windows giant Anderson gives solar window integration a $30M boost
Here at The Optimist Daily, we love sharing stories about the exciting advancements that we are making in terms of discovering and fashioning creative ways that we can harvest clean, green, and renewable energy. One of the threads of renewable energy we’ve been following closely is solar Read More...
‘Strange metal’ may be the future for a more energy efficient world
Strange metal behavior was first noticed around 30 years ago. These materials are composed of copper-oxides and carry the properties of being high-temperature superconductors. This means they can transfer electricity very efficiently, withstanding much higher temperatures with less energy loss than Read More...
China’s “artificial sun” fusion reactor breaks yet another record
The Chinese Academy of Sciences has exciting news about its fusion reactor that it recently shared in a release. The Experimental Advanced Superconducting Tokamak (EAST) fusion reactor successfully sustained a plasma temperature of 120 million degrees Celsius for 1,056 seconds, effectively Read More...
Ocean Battery could help solve the renewable energy storage problem
The lack of adequate energy storage systems is one of the biggest problems associated with the rise of renewables such as wind and solar in recent years. In an effort to provide a solution, a Dutch startup has invented the Ocean Battery — an energy storage system that operates by the same Read More...
Engineers develop hydrogen-powered eCargo bikes
In recent years, green hydrogen has been identified as an increasingly attractive clean energy source that could help accelerate our transition away from fossil fuels. And while we’ve seen hydrogen-powered trains, planes, and even boats, it seems like bikes have been left behind — that is, Read More...
Modular facade can be installed onto old buildings to cut their emissions
Heating and cooling our buildings comes with a hefty environmental footprint. In the US alone, heating and cooling systems account for 38 percent of greenhouse gas emissions of residential housing. Coming up with more sustainable ways to maintain a favorable temperature within our homes is thus key Read More...
Your future rooftop could be made out of easy-to-install solar shingles
The roofs of the future may be made entirely out of solar panels. At least that’s the goal of GAF Energy, which has recently launched a new solar roof that it believes can revolutionize the future of the roofing industry by making it an integral part of our green energy transition. “The Read More...
New York City moves away from natural gas in new buildings
As cities scramble to meet their ambitious emissions reduction goals, local governments are increasingly looking to shift from fossil fuels to cleaner forms of energy. New York City, for example, has become the latest major city to ban the use of natural gas in new buildings, reports Reuters. As Read More...
New Jersey is first eastern state to start phasing out diesel powered trucks
In the latter half of December 2021, New Jersey became the first east coast state to begin the process of phasing out diesel-powered trucks (meaning anything bigger than a delivery van). The plan, which is based on California’s Advanced Clean Trucks rule (ACT), is expected to roll out in 2025 and Read More...
